Assessment of Critical Loads due to the Negative Form of Technogenic Relief

Authors: Kravchenko T. I., Filatov V. V.

The article is devoted to the plane problem of appraisal critical effort, appearing in a flaky- horizontals model of a weak grunt environment under the influence of loading, the kind of which has a form of an symmetrical triangular and semi-infinite combined load.

Petrogenic Water, Hydrothermal Process and Oil Migration in a Tectonically Activated Buried Continental Rift (West Siberia)

Authors: Korobov A. D., Korobova L. A.

It was established that with convective heat and mass transfer in the region of the Krasnoleninskij swell (West Siberia), the pulsating lateral pressure regime used to contribute to interlayer water avalanche liberation from the Upper Jurassic-Lower Cretaceous smectites in the process of their hydromicatization. The resurgent (petrogenic) water constituted the basis of the hydrothermal solutions responsible for the processes of ultra-acid leaching, metasomatosis, hydrocarbon generation and migration.

Features of Rhythostratigraphy of Halogen Thicker and Paleogeographic Conditions of Potassium-Magnesium Mineralization in the Southwestern Deadlock Part of North-Caspian Halmeic Basin

Authors: Svidzinskiy S. A., Baranovskaya M. A.

Provides rhythmostratigraphic characteristic of Lower Permian halogen formations of Western monoclinal part of the North-Caspian halmeic basin. Paleogeographic conditions of accumulation of potassium and magnesium and magnesium deposits in the Volga Monocline and the southern deadlock part that holds Gremyachinskoe deposit and related search sites: Darganovskiy and Ravninniy are considered.

Estimation of Soil Cover mobile and total Forms of heavy Metals Pollution in Zone of Guselskogo Landfill Solid waste Influence (Saratov)

Authors: Pavlov P. D., Reshetnikov M. V., Eremin V. N.

The studies to determine the concentration of mobile and total forms of heavy metals. Assessed by an excess of total and mobile forms of heavy metals in the soil cover over the set of MPC and evaluated geochemical transformation of soils by analyzing their total fertility heavy metal pollution.

Hydrocarbon natural tectonic Pump and secondary dolomitization as a Result of tectonic-hydrothermal Activity in a rift sedimentary Basin

Authors: Korobov A. D., Korobova L. A., Akhlestina E. F., Kolotukhin A. T., Mukhin V. M.

The linear trend of secondary dolomitization development within the Tevlinsko-Russkinskoye field has been found to traverse the tectonically contrasting, closely adjacent and hydrodynamically  interconnected compression-tension zones. This provides rationale for origination of a natural tectonic pump in the field.

Posible Sources of magnetic Anomalies in the South of Precaspian Depression

Authors: Guzhikov A. Y., Pronin A. P.

In connection with Carboniferous, Permian and Triassic rocks, marked by magnetic susceptibility of thousand and dozens of thousands (10-5 SI units) that are located in southern part of Precaspian Depression, samples of these rocks were studied in details, using strongly magnetic samples. The possible effects of anomalous magnetic field were counted on the base of received data.

Reconstruction of the Late Vasyuganian Sedimentation Settings Within the Middle of Group of Fields

Authors: Goncharenko O. P., Astarkin S. V., Dzhoni S. N.

The paper deals with the results of complex lithology-facies examination of the UV1 1 layer within the Middle Ob group of fields. It is found that in the area under investigation, the layer was formed in the littoral-marine and shallow-water marine conditions under the effect of waves and currents. A paleogeographic chart has been constructed for the period of the UV1 1 layer generation in the Vasyuganian formation; forecast has been made as to the development of improved reservoir rocks.

Petromagnetic and Thermomagnetic Characteristic of Soils in the Area of ≪Oktyabrskiy≫ Landfill Waste Disposal (Saratov)

Authors: Sheshnev A. S., Reshetnikov M. V.

Investigations of the physical parameters (magnetic susceptibility, thermal-magnetic effect) and soil texture and soil in the area of the landfill waste disposal. Performed a preliminary assessment of technogenic pollution of soils and soil heavy metals and petroleum products.

Mineral Resources of Khvalynsk District (Saratov Region) in the Health Resort Business Development

Authors: Samoilov A. G., Zozyrev N. Y.

Khvalynsk district of Saratov region has unique balneotherapeutic characteristics that led to development of a climate resort network, including alpine skiing resort. However, the resort health effect can be enhanced by the use of local mineral resources: medicinal ground waters and clays.

Unitary Late Cretaceous Hexactinellids (Porifera)

Authors: Pervushov E. M.

Hexactinellids comprise diverse types of sponges viewed as solitary ones. They used to constitute the basis of sponge communities in the Middle-Late Jurassic and Middle Cretaceous of the European region. The morphological diversity of unitary forms is determined by the skeletal structure with combination of a goblet, a shaft, a false shaft and a system of rhizoids. The goblet wall is peculiar for the highest morphological flexibility, which contributes to substantial habitus changes of the skeleton original morphotypes.
